Abstract (en)
[origin: EP2537708A2] A headlamp for a vehicle includes a light source (15, 15R, 15G, 15B) adapted to emit a spotlight (S), a lens (16, 16R, 16G, 16B) adapted to receive and transmit the spotlight, a lens actuator (17, 17R, 17G, 17B) adapted to adjust a size (D) of the spotlight transmitted through the lens, a two-dimensional optical deflector (18) adapted to deflect the spotlight from the lens to an illumination area ahead of the vehicle, and a control circuit (19) configured to control the lens actuator in such a way that irregularity of illumination in the illumination area is avoided.
